Ultra-high-voltage electricity transmission in China ... electricity transmission (UHV electricity transmission) has been used in China since 2009 to transmit both alternating current (AC) and direct current (DC) electricity over long distances separating China's energy resources and consumers. Expansion of both AC and DC capacity continues in order to match generation to consumption demands while minimizing transmission losses.

Gis | Electrical Substation | Insulator (Electricity) Insulated Substations. INTRODUCTION • For maintaining proper voltage levels at transmission and distribution level and for providing greater stability a number of electrical transformation and switching setups have to be created in between generating station and consumer ends. These transformation and switching setups are generally known as electrical substations.
